A loaded grocery cart is rolling across a parking lot in a strong wind. You apply a constant force to the cart as it undergoes a displacement How much work does the force you apply do on the grocery cart?

Solution 8E Step1: Work W is dot product or scalar product of force vector F and displacement vector s. W=F.s Work = Force * distance W = F * s W = product of the x components + product of the y components W = (Fx * sx) + (Fy * sy) Step 2: Given data: Constant force F = (30 N) i (40 N) j Displacement S = ( 9.0 m) i (3.0 m) j
